Title: Process for the production of tubular objects of prestressed concrete
IPC: B28B21/62
Filed: 1946-03-01
Abstract: 608,812. Moulding concrete pipes. EDWIN, E., and NILSEN, N. D. March 1, 1946, No. 6432. Convention date, Nov. 24, 1943. [Class 87(ii)] In the method of producing a concrete pipe by winding stressed wire on a hardened concrete inner pipe 1 and then casting an outer concrete pipe 5 thereon, the inner pipe is subjected to an internal pressure which balances the stress produced by the wire during the hardening of the outer pipe in order that the completed pipe may have equal stress throughout. The pressure is produced by placing a cap 2 at each end of the pipe and introducing water or gas under pressure. Water may be introduced into a bag 7 in the pipe. The adhesion between the outer and inner pipe may be increased by radial reinforcement such as wavy wire arranged parallel to the axis of the pipe, or lengths of unit may project from the winding wire.

Abstract: 1412064 Fuel injection pumps SULZER BROS Ltd 9 Feb 1973 [17 Feb 1972] 6511/73 Heading F1A A fuel injection pump comprises a spill valve 10 opened by a lever 16 to terminate delivery, the lever 16 being pivotable on a pin 19 eccentrically mounted on an angularly adjustable shaft 20 with an eccentricity e which ensures that the effective eccentric arm is longest when the pump is set for minimum delivery. Delivery is increased by leftward movement of a governor controlled rod 23 connected to a lever 22 attached to the shaft 20 and urged to the minimum delivery position by a spring 25. Initially angular adjustment of the shaft 20 causes a large rate of lowering of the lever 17 but this decreases to a minimum with continued movement. A pointer 27 fixed to the shaft 20 cooperates with a scale to provide an indication of the delivery. The lever 16 and a lever 15 controlling a suction valve 8 are operated by the pumping plunger 2.

Title: Process for the manufacture of tetrafluoro-benzoquinone-1 : 4
Filed: 1958-03-04
Abstract: The invention comprises tetrafluoro-benzoquinone-1:4, and processes of making it from tetrachloro-benzoquinone-1:4 by reaction with potassium fluoride.  According to one method, the dry tetrachloro-benzoquinone is conducted in vapour form over heated dry potassium fluoride, and in an alternative method, the dry tetrachloro-benzoquinone is reacted with dry potassium fluoride at a raised temperature, the tetrafluoro-benzoquinone so p  obtained is reduced to the corresponding hydroquinone, the latter is purified by distillation with toluene vapour, and the purified hydroquinone compound is converted by oxidation into tetrafluoro-benzoquinone-1:4. Reaction with potassium fluoride may be carried out at a temperature within the range of 175 DEG -350 DEG C.  The reaction product may be purified by sublimation e.g. under reduced pressure.  In an example, potassium fluoride is dried in a drying chamber, then ground and charged into part of a reaction tube which is then heated at 350 DEG C. while passing dry nitrogen through it, water vapour being expelled from the fluoride and passed to an absorption apparatus.  A mixture of dry chloranil and calcium fluoride is then charged into the tube, and then a portion of calcium fluoride only.  The tube is heated to 320 DEG C. and nitrogen is passed through.  The product separates out as a sublimate in a receiver attached to the reaction tube.  The product is soluble in benzene toluene, alcohol, ether, chloroform, carbon tetrachloride, petroleum ether, and 1-dichlorofluoro-2-dichlorofluoro-ethane.  In another example, a mixture of dry potassium fluoride and chloranil is heated in a glass tube at 105 DEG C. under a pressure of 20 mm. Hg. for several hours and then brought to a reaction temperature of 320 DEG C.  The products formed are sublimed out of the hot zone by again reducing the pressure.  The sublimed substance is dissolved in toluene and hydrogenated in presence of platinic oxide. Tetrafluoro-hydroquinone-1:4 is obtained from the solution by crystallisation.  This compound is dissolved in ether and mixed with calcined magnesium sulphate and active lead dioxide and the mixture is shaken vigorously.  The solution is passed through a filter into a sublimation apparatus and after distillation of the ether, the tetrafluoro-benzoquinone-1:4 is sublimed out at 50 DEG C. under a pressure of 15 mm. Hg. Tetrafluoro-benzoquinone-1:4 may be used as a fungicide, or as an agent for controlling the polymerisation of olefines and vinyl compounds.ALSO:1-Dimethylamino-4-aminobenzene is oxidized to "Wursters' Red" using tetrafluorobenzoquinone 1 : 4 as oxidizing agent.

Thermoplastic bodies are divided by rubbing a portion of the body until the frictional heat generated melts the portion of the body being rubbed. A thin disc or ring 1 with a blunt edge is fixedly mounted on a rotatable shaft 6 and is supported on either side by discs 2 of lesser diameter. The thermoplastic body 5 is moved towards the disc 1 on a support 3 with a groove 4 adapted to receive the edge of the disc 1. The support 3 is so positioned that the angle formed between the top surface of the body 5 and the tangent of the disc 1, where it cuts the body 5, is between 5 and 20 degrees, but preferably between 10 and 15 degrees. The disc 1 is so rotated that the linear movement of its cutting edge, nearest the support 3, is opposite in direction to the movement of the thermoplastic body 5. Upon contact between the body 5 and the rotating disc 1, heat is generated which melts the body 5. The rotational movement of the disc 1 keeps the disc cool, but forced draught cooling may be utilized. In a modification an endless strip is used in place of the disc 1.
